Question

what is the potential energy if a body of mass 250kg is at a height of 30 meter​

Answer 1

Answer:

250 kg multiplied by 30 m=7500

Answer 2

Given:

⟹ mass of the body = 250 kg

⟹ height = 30 m

To Find: potential energy of the body.

Solution:

⟼ Potential energy = Mgh

where,

m = mass; g = acceleration due to gravity;

h = height.

➢ We know that the acceleration due to gravity on Earth is 9.8 m/s²

⟼ P.E = Mgh

⟼ P.E = 250 kg × 9.8m/s² × 30 m

⟼ P.E = 73,500 kg m²/s²

✪ we know that kg m²/s² can be expressed in joule.

∴ The potential energy of the body is 73,500 joule
